Titanium Buttweld Fittings
Titanium Buttweld Fittings are high-performance piping components designed for joining, branching, reducing, or redirecting flow in pipelines. Manufactured using superior-quality titanium alloys—mainly Grade 2 (Commercially Pure Titanium) and Grade 5 (Ti-6Al-4V)—these fittings are valued across industries for their lightweight strength, excellent corrosion resistance, and long service life.
With their robust properties, titanium fittings are widely used in aerospace, marine, chemical processing, oil & gas, desalination, medical, and power generation sectors. The buttweld design provides a smooth, leak-proof connection, ensuring high reliability even under extreme operating conditions.
Chemical Composition
The exceptional properties of titanium buttweld fittings stem from their chemical makeup:
Titanium Grade 2 (Commercially Pure Titanium)
Ti: 99.2% min
C: 0.1% max
N: 0.03% max
O: 0.25% max
Fe: 0.3% max
H: 0.015% max
Known for its outstanding corrosion resistance and high ductility, Grade 2 is used in seawater environments, chemical plants, and medical devices where purity and formability are critical.
Titanium Grade 5 (Ti-6Al-4V)
Ti: 90% min
Al: 6% min
V: 4% min
O: 0.2% max
Fe: 0.25% max
This alloy offers exceptional strength and toughness while retaining corrosion resistance. It is the most commonly used titanium alloy, particularly in aerospace and offshore applications where performance under stress is vital.
Mechanical Properties
Titanium Grade 2
Density: 4.5 g/cm³
Tensile Strength: 344 MPa (49,900 psi)
Yield Strength: 275 MPa (39,900 psi)
Melting Point: 1665 °C (3030 °F)
Elongation: 20%
Titanium Grade 5
Density: 4.43 g/cm³
Tensile Strength: 950 MPa (138,000 psi)
Yield Strength: 880 MPa (128,000 psi)
Melting Point: 1632 °C (2970 °F)
Elongation: 14%
These properties highlight why titanium fittings are chosen for applications that demand both strength and corrosion resistance. Grade 2 is ideal where ductility and corrosion protection are needed, while Grade 5 is the preferred choice for high-pressure, high-temperature conditions.
